No, but I'm all ears.
Jones' closest call during his Grand Slam year was in the first of the four events: the Amateur Championship at St. Andrews, where he had to come from behind in his fourth-round match against Cyril Tolley. At the 17th, Jones had driven left and had no angle to the flag, and decided on playing around to the left of the Road bunker, which almost no one ever does.
The match had a huge gallery, and Jones did his best to get the marshals to move them back before playing the shot, because the gallery might unfairly backstop his ball from going in the Swilcan Burn. Nevertheless, the ball did go into the gallery, and some people questioned the play afterwards. I can't remember if he won the hole or just got a key half, but it was written about for many years: Jones wrote about it in GOLF IS MY GAME, which is why I remember it.
Jones actually won the match at the 19th, putting his third shot between Tolley's ball and the hole for a stymie, which Tolley could not negotiate.
